Optical telescopes utilize refraction and reflection to focus light, enabling detailed astronomical observations and ...

X‐ray optics has emerged as a critical field in modern imaging and fabrication, utilising refractive lenses that enable the precise control and focusing of X‐ray beams. Refractive lenses, particularly ...

Researchers are making progress toward a “perfect lens” that will be able to resolve an organelle assembling a protein or a virus attacking a cell. From ribosomes assembling proteins to viruses ...

Physicists in the US have demonstrated negative refraction at optical wavelengths for the first time. Vladimir Shalaev and colleagues at Purdue University obtained the result in a material consisting ...

ABSTRACT Astronomical optics may encounter a wide range of nighttime temperatures (∼−10°C to +20°C) at mountaintop observatories. Complex refractive optics used in high‐performance spectrographs and ...

NASHVILLE, Tenn. — Wave-guided optics application technology may now help patients with keratoconus, according to a speaker at Optometry’s Meeting. “We know a lot of our irregular cornea patients ...

Exploiting a novel technique called phase discontinuity, researchers have induced light rays to behave in a way that defies the centuries-old laws of reflection and refraction. The discovery has led ...

Biophotonics imaging techniques are yielding ever clearer views of structures and processes within tissues and cells, but the inherent scattering behavior of those tissues is a constant inconvenience.

An unusual optical phenomenon explains why the Titanic struck an iceberg and received no assistance from a nearby ship, according to new research by British historian Tim Maltin. Atmospheric ...
